Abstract
Convolutional neural network models are developed to predict the aerodynamic coefficients from images of the flow field of an airfoil under dynamic stall. The networks are capable of identifying relevant flow features present in the images and associate them to the airfoil response. Results demonstrate that the models are effective in interpolating between flow parameters. Now, research is being done to verify the extrapolation capacity of the models, which will be presented in the final version of the paper. Preliminary results show that CNN-based models may offer a promising alternative for sensors in experimental campaigns and for building robust surrogate models of complex unsteady flows.
